Copper Chromium Zirconium

The addition of Zirconium Chromium Copper Alloy improves creep resistance at high operating temperatures and reduces sticking of electrodes to the work during spot welding of galvanized/coated materials. C18150 is specified mainly for electrode application. Chromium Zirconium is a RWMA Class 2 material and is stronger than the RWMA Class 1 materials.
